What does a precipitation rate measured in inches per hour help determine?

A precipitation rate measured in inches per hour is a critical indicator of the efficiency of an irrigation system. This measurement tells landscape contractors how quickly water is delivered to the landscape, which is essential for understanding whether the irrigation system is applying water at a rate that the soil can absorb without causing runoff or excessive pooling.

By evaluating the precipitation rate, contractors can determine if the irrigation system is functioning properly. For example, if the rate is too high, it may suggest that water is being applied faster than the soil can infiltrate, leading to waste. Conversely, if the rate is too low, it might not provide sufficient moisture to the plants, affecting their health and growth.

Understanding this rate is important for scheduling watering practices effectively—ensuring that plants receive the right amount of water for optimal growth without overwatering, which can lead to issues such as disease and waterlogging. Thus, knowing the precipitation rate directly contributes to optimizing irrigation efficiency and promoting sustainable landscape management.
